Пропадает звук плеера при сворачивании навигатора

[mak]

1. Устройство  - магнитола в авто, платформа Cortex A9 MST786 Dual Core 1GHZ

2. Стоковая прошивка Android 4.2.2, system version 2.7.40
3. Плеер и разблокировку покупал через сайт Poweramp(вроде бы как).
Проблема такая: включаю музыку на виджете на главном экране, потом запускаю Яндекс.Навигатор. Еду по маршруту, слушаю музыку. Потом решаю сменить альбом, для этого нажимаю кнопку "Back" или "Home" на магнитоле, чтобы свернуть Яндекс.Навигатор. Из верхней панели пропадает значок "Координаты по GPS" и воспроизведение музыки тоже останавливается. При это если открываю Я.Навигатор обратно, значок "Координаты по GPS" появляется и музыка автоматически начинает играть. 
Чтобы продолжить пользоваться музыкой, мне требуется включать радио а потом обратно Poweramp, т.к. у Poweramp перестают работать кнопки воспроизведения, т.е. музыка не играет, хотя значки меняются.
В Настройках магнитолы приоритеты в настройках "Звук" менял, не помогло.
Помогите плз.

Таск киллеров и проч. не стоит
